ENETC ports can manage the MDIO bus via local register interface. However there's also a centralized way to manage the MDIO bus, via the MDIO PCIe endpoint device integrated by the same root complex that also integrates the ENETC ports (eth controllers). Depending on board design and use case, centralized access to MDIO may be better than using local ENETC port registers. For instance, on the LS1028A QDS board where MDIO muxing is required. Also, the LS1028A on-chip switch doesn't have a local MDIO register interface. The current patch registers the above PCIe endpoint as a separate MDIO bus and provides a driver for it by re-using the code used for local MDIO access. It also allows the ENETC port PHYs to be managed by this driver if the local "mdio" node is missing from the ENETC port node. Signed-off-by:

Andrew Jeffery authored
phy-handle is necessary for the AST2600 which separates the MDIO controllers from the MAC. I've tried to minimise the intrusion of supporting the AST2600 to the FTGMAC100 by leaving in place the existing MDIO support for the embedded MDIO interface. The AST2400 and AST2500 continue to be supported this way, as it avoids breaking/reworking existing devicetrees. The AST2600 support by contrast requires the presence of the phy-handle property in the MAC devicetree node to specify the appropriate PHY to associate with the MAC. In the event that someone wants to specify the MDIO bus topology under the MAC node on an AST2400 or AST2500, the current auto-probe approach is done conditional on the absence of an "mdio" child node of the MAC.

The AST2600 design separates the MDIO controllers from the MAC, which is where they were placed in the AST2400 and AST2500. Further, the register interface is reworked again, so now we have three possible different interface implementations, however this driver only supports the interface provided by the AST2600. The AST2400 and AST2500 will continue to be supported by the MDIO support embedded in the FTGMAC100 driver. The hardware supports both C22 and C45 mode, but for the moment only C22 support is implemented. Signed-off-by:

In commit 365ad353 ("tipc: reduce risk of user starvation during link congestion") we allowed senders to add exactly one list of extra buffers to the link backlog queues during link congestion (aka "oversubscription"). However, the criteria for when to stop adding wakeup messages to the input queue when the overload abates is inaccurate, and may cause starvation problems during very high load. Currently, we stop adding wakeup messages after 10 total failed attempts where we find that there is no space left in the backlog queue for a certain importance level. The counter for this is accumulated across all levels, which may lead the algorithm to leave the loop prematurely, although there may still be plenty of space available at some levels. The result is sometimes that messages near the wakeup queue tail are not added to the input queue as they should be. We now introduce a more exact algorithm, where we keep adding wakeup messages to a level as long as the backlog queue has free slots for the corresponding level, and stop at the moment there are no more such slots or when there are no more wakeup messages to dequeue.

Vivien Didelot says: ==================== net: dsa: mv88e6xxx: avoid some redundant VTU operations The mv88e6xxx driver currently uses a mv88e6xxx_vtu_get wrapper to get a single entry and uses a boolean to eventually initialize a fresh one. However the fresh entry is only needed in one place and mv88e6xxx_vtu_getnext is simple enough to call it directly. Doing so makes the code easier to read, especially for the return code expected by switchdev to honor software VLANs. In addition to not loading the VTU again when an entry is already correctly programmed, this also allows to avoid programming the broadcast entries again when updating a port's membership, from e.g. tagged to untagged. This patch series removes the mv88e6xxx_vtu_get wrapper in favor of direct calls to mv88e6xxx_vtu_getnext, and also renames the _mv88e6xxx_port_vlan_add and _mv88e6xxx_port_vlan_del helpers using an old underscore prefix convention. In case the port's membership is already correctly programmed in hardware, the following debug message may be printed: [ 745.989884] mv88e6085 2188000.ethernet-1:00: p4: already a member of VLAN 42 ==================== Signed-off-by: -

Paul adds support for reporting what the link partner is advertising for flow control settings. Jake fixes the hardware statistics register which is prone to rollover since the statistic registers are either 32 or 40 bits wide, depending on which register is being read. So use a 64 bit software statistic to store off the hardware statistics to track past when it rolls over. Fixes an issue with the locking of the control queue, where locks were being destroyed at run time. Tony fixes an issue that was created when interrupt tracking was refactored and the call to ice_vsi_setup_vector_base() was removed from the PF VSI instead of the VF VSI. Adds a check before trying to configure a port to ensure that media is attached. Brett fixes an issue in the receive queue configuration where prefena (Prefetch Enable) was being set to 0 which caused the hardware to only fetch descriptors when there are none free in the cache for a received packet. Updates the driver to only bump the receive tail once per napi_poll call, instead of the current model of bumping the tail up to 4 times per napi_poll call. Adds statistics for receive drops at the port level to ethtool/netlink. Cleans up duplicate code in the allocation of receive buffer code. Akeem updates the driver to ensure that VFs stay disabled until the setup or reset is completed. Modifies the driver to use the allocated number of transmit queues per VSI to set up the scheduling tree versus using the total number of available transmit queues. Also fix the driver to update the total number of configured queues, after a successful VF request to change its number of queues before updating the corresponding VSI for that VF.

Currently, the reset interrupt is cleared in the reset task, which is too late. Since, when the hardware finish the previous reset, it can begin to do a new global/IMP reset, if this new coming reset type is same as the previous one, the driver will clear them together, then driver can not get that there is another reset, but the hardware still wait for the driver to deal with the second one. So this patch clears PF's reset interrupt status in the hclge_irq_handle(), the hardware waits for handshaking from driver before doing reset, so the driver and hardware deal with reset one by one. BTW, when VF doing global/IMP reset, it reads PF's reset interrupt register to get that whether PF driver's re-initialization is done, since VF's re-initialization should be done after PF's. So we add a new command and a register bit to do that. When VF receive reset interrupt, it sets up this bit, and PF finishes re-initialization send command to clear this bit, then VF do re-initialization.

Currently, the driver sets handshake status to tell the hardware that the driver have downed the netdev and it can continue with reset process. The driver will clear the handshake status when re-initializing the CMDQ, and does not recover this status when reset fail, which may cause the hardware to wait for the handshake status to be set and not being able to continue with reset process. So this patch delays clearing handshake status just before UP, and recovers this status when reset fail. BTW, this patch adds a new function hclge(vf)_reset_handshake() to deal with the reset handshake issue, and renames HCLGE(VF)_NIC_CMQ_ENABLE to HCLGE(VF)_NIC_SW_RST_RDY which represents this register bit more accurately.
